To all whom it may conccrmi Be it known that I, TRUMAN G. PADDACK, acitizen of the United States, residing' in the city of IVyOming, countyof Hamilton, and State of Ohio, have invented certain new and usefulImprovements in Cutting-halachines for Severing Soft and Pliable Material, of which the following is a full,.clear, and exact description,reference being had to i the accompanying drawings, forming part of thisspecification.

lll/Iy invention relates to cutting machines in which rapidly revolvingcutting or sliding disks or saws are provided in connection with a tableupon which the material to be cut is fed to the disks, and the especialobject of my invention is to provide a machine in which very soft cardedor garneted material such as cotton wadding and cotton batting may bereadily and easily severed into strips. Such material is ordinarily verydifficult to sever when fed to a rapidly revolving disk, knife or saw,because the fibers is alniost immediately packed in around the slot inthe table and prevents the cutting disk from doing its work, nor is itpossibleto aceol'njiilish the result by feeding the material betweenrollers, one of which is provided with a cutting edge, either with orwithout a corresponding groove in the other roller to receive thecutting edge. With suoli constructions the fibers accumulate under theedge of the knife and prevent a proper severance. I overcome thisdifficulty by the construction hereinafter particularly pointed out andclaimed, in which a thin plate is provided slotted to embrace thecutting edge of the disk, and with free spacer below the plate toprevent the accumulation of fibers.

In the drawings Figure 1 is a front elevation of the upper portion of myimproved machine broken away in part, and illustrating two cuttingdisks. Fig. 2 is a cross section taken on the lines 2, of Fig. 1. Fig. 3is a plan view of a portion of the machine with a section of the cuttingedge of the cutting disk taken on lines 8, 3 of Fig. 2.

l is the table of the machine supported on usual standii ds 5, 5, atconvenient height, and upon this table is mounted the shaft 6 providedwith the usual journal bearings 7, 7, the shaft being driven at a highrate of speed by the driving pulley 8, or in any other convenient wayfrom suitable power. Upon l l l this shaft cutting disks 9, 9, of anydesired number, are secured by the hubs 10, 10, and `set screws 11, l1or in any other convenient way, and the lower edge of the disks ride inslots 12, in the table, the walls of the slots being cut to spread outdownwardly as shown, in order to prevent the accumulation of lint andfibers from the material cut which would tend to retard and dull theaction of the cutting disks.

13 is a block or bar which is secured across the table from side to sideimmediately in front of the the feeding side, and the disks are rotatedfrom right to leftor toward ther operator from above downward. Mountedon this block 13, is a thin plate 14, one for each cutting disk. Thisplate is provided with a narrow V-shapedV slot 15 to embrace the bevelededge 16 of the cutting disk, and the side edges of the slot in the plateare formed to lit very closely to this beveled edge without contactingtherewith. The block 13 is of such a height that there will be ampleclearance space between the plate and the top surface of the table toprevent the accumulation of fiber between the plate and the table, andthe plate extends inwardly at such an angle to the cutting edge of thedisk, that a proper shearing cut will be given the material as it is fedto the cutter.

I-Iaving thus described my invention what I claim as new and desire tosecure by Letters Patent, is:

1. In a machine of the character specified, the combination with a feedtable upon which the material to be cut is fed, said table provided witha narrow slot, and a cutting disk mounted above the table surface torotate thereon, with the edge of the disk projecting into said slot, ofma plate slotted to embrace the cutting edge" of the disk, mounted in aplane parallel with and above the surface plane of the table, and overwhich plate the material to be cut is fed to the knife.

2. In a machine of the character specified, the combination with a feedtable upon which the material to be cut is fed, said table provided witha narrow slot and a cutting disk mounted above the table si'lrfaee torotate thereon with the edge of the disk projecting into said slot, of aplate slotted to embrace. the cutting edge of the disk, mounted in aplane parallel with and above the surface plane of the table, and overwhich plate cutting disks upon the material to be cut is fed to theknife, said plate being presented to the cutting edge at an angle to theradial lines of the disk to give a shearing cut.

8. In a machine of the character speciiied, the combination with a feedtable upon which the material to be cut is fed, said table provided witha series of narrow slots and a corresponding series of cutting disksmounted above the table surface to rotate thereon with'the edges of thevdisks projecting each into its respective slot, of a bar secured acrossthe tableinfront of the cutting i surface of disks, and a thinplatevmounted Von the top said bar' in a plane parallel with f thesurface plane of the table and extending toward' the disk with narrowslots in said 'plate one for each disk, the sides of which slots eachembrace the cutting edges of their respective disks.

4L. In a machine of the character specified, the combination with atable upon which the material to be cut is fed, said table provided witha narrow slot, the walls of which spread out downwardly, and a cuttingdisk mounted to rotate on the table with the edges of the disk projecting into said slot, of a thin plate slot-ted to embrace the cuttingedge of the disk, mounted in a plane parallel with and above the surfaceplane of the table, and over which plate the material to be cut is fedto the knife.
